  • Features & Performance
  • Product Parameters

Heating&hot water
Intelligently control
the household temp

Heating&hot water functions adopt four-point temp. control tech.,
which effectively controls the temp. and shortens the heating time,
and the temp. difference of hot water is as low as ±1°C;
3 heating modes, matching different heating needs,
saving time and energy; 3 stages combustion tech.,
combustion heat load ratio is 1:8, and the firepower
can be large or small, so as to eliminate the problem
of enough hot water in winter and too-hot water in summer,
and enjoy a comfortable bathing experience at all times.

Four-point temp. control tech.
More Rapidly heating, ±1°C hot water temp. difference

By monitoring the heating temp. at multiple points, the heating state can be adjusted in real time,
and the hot water output temp. can be kept constant while ensuring fast heating.

3 heating models
Matching different heating needs, save time and energy

Providing 3 heating modes of home, going out, and sleep, and users can switch at will. While ensuring comfortable heating,
it can effectively save energy and match different heating needs.

3 stages combustion
No scalding skin in
Summer bath
Enough warmth in winter bath

Intelligent 3-stage adjustable firepower, the lowest temp.
rise is as low as 6K, and it is easy to achieve a comfortable
bathing experience with stable hot water temp.
rise in summer and strong firepower in winter.

Laminated high-precision screen

Easy operation with one touch, intuitive parameter display

42db low noise

Low-vibration design structure and sealing material treatment are adopted to suppress the running noise from the source and structure.

Power off memory

Intelligently back up the working status,
restarting after power failure, auto read the working
status information before, no need to reset.
